2,5-Dioxopyrrolidin-1-yl 3′,6′-dihydroxy-3-oxo-3H-spiro[isobenzofuran-1,9′-xanthene]-5-carboxylate (cas: 92557-80-7) belongs to benzofurans derivatives. Many natural or synthetic compounds containing benzofuran skeletons have been found to possess remarkable activity as agrochemicals and pharmaceuticals. Benzofurans are stable towards alkali and readily polymerize on treatment with sulfuric acid, due to which they are useful for the preparation of low cost chemically relatively inert resins.SDS of cas: 92557-80-7

Fluorescent Nanoparticles for Multiplexed Bacteria Monitoring was written by Wang, Lin;Zhao, Wenjun;O’Donoghue, Meghan B.;Tan, Weihong. And the article was included in Bioconjugate Chemistry in 2007.SDS of cas: 92557-80-7 This article mentions the following:

Rapid, sensitive, and selective detection of pathogenic bacteria is extremely important for proper containment, diagnosis, and treatment of diseases like foodborne illness, sepsis, and bioterrorism. Most current bacterial detection methods are time-consuming and laborious and can detect only one bacterial pathogen at a time. The authors have developed a method for sensitive, multiplexed monitoring of bacterial pathogens within 30 min using multicolored FRET (fluorescence resonance energy transfer) silica NPs (nanoparticles). By varying the ratio of three tandem dyes coencapsulated into the NPs, the authors have synthesized NPs that emit unique colors upon excitation with a single wavelength. When these NPs were conjugated to monoclonal antibodies specific for the pathogenic bacteria species Escherichia coli, Salmonella typhimurium, and Staphylococcus aureus, and then incubated with small concentrations of the bacteria, simultaneous and sensitive detection of the multiple bacterial targets was achieved. In the experiment, the researchers used many compounds, for example, 2,5-Dioxopyrrolidin-1-yl 3′,6′-dihydroxy-3-oxo-3H-spiro[isobenzofuran-1,9′-xanthene]-5-carboxylate (cas: 92557-80-7SDS of cas: 92557-80-7).
